I want the body of my page to slide, but I couldn't get it to work. Widgets on the page compress themselves instead of sliding. When I use single child scrollview, I get a hassize error. If you could help with this situation, I would greatly appreciate it. so far I have used singlechildscrollview and custom scroll but without success. I don't know if there is something I've overlooked. I will be glad if you help

EDIT

I edited my custom body widget like this but the result did not change.

class CustomBody extends StatelessWidget {
  final Widget? child;
  final double height;

  CustomBody({Key? key, this.child, required this.height}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Stack(
      children: [
        Align(
          alignment: Alignment.bottomCenter,
          child: CustomScrollView(
            shrinkWrap: true,
            slivers: [
              SliverToBoxAdapter(
                child: Container(
                  height: height,
                  decoration: BoxDecoration(
                    color: Colors.white,
                    borderRadius: BorderRadius.only(
                      topLeft: Radius.circular(60),
                      topRight: Radius.circular(60),
                    ),
                  ),
                  child: child,
                ),
              ),
            ],
          ),
        ),
      ],
    );
  }
}

CodePudding user response：

Did you try putting singlechildscrollview on custombody?

CodePudding user response：

cannot be more than 1 Expanded widget in a column. the best option is using a CustomScrollView like this :

Scaffold(
      appBar: AppBar(),
      drawer: Drawer(),
      body: CustomScrollView(
        slivers: [
          SliverList(
            delegate: SliverChildListDelegate(
              [

                Container(height: 50, color: Colors.green), // your widget here
                Container(height: 50, color: Colors.green), // your widget here
                Container(
                  height: 300,
                  color: Colors.grey,
                  child: Column(
